Copilot sidebar for Chrome is an unofficial port that opens Microsoft Copilot in Chrome's side panel, aware of the page you are viewing. It is for people who like the Copilot sidebar in Edge but browse mainly in Chrome.
Open Chrome's side panel and select the Copilot sidebar, then chat with Copilot about the page in front of you.
This is not a Microsoft product, and it depends on Microsoft's Copilot service, so changes on Microsoft's side can affect how it works. Page content is shared with Copilot.
